Definitions
- the present invention relates to a method of production control and, more particularly, to a method of production control that is preferably used for the manufacture of electronic apparatus such as liquid crystal displays.
- Article 1 Japanese Patent Application
- a load ratio of each of the production steps that is the ratio of the number of products to be processed at the production step to the product processing capability of the production step is first obtained as the ratio of planned cumulative production at the production step to cumulative capability of the production step throughout an operating period that is the object of a medium-term production plan.
- an optimum ratio of use of each apparatus at each production step is calculated such that the production steps have an equal load ratio.
- a processing schedule for each production step is determined such that the ratio of use of each apparatus at each production step substantially equals the optimum ratio of use during the operating period.
- Article 1 has proposed a method of production control to be used for a group of production steps belonging to a production line for two ore more product types when there is a condition that the history of an apparatus used for processing one product type at one of the production steps limits processing of one product type at another of the group of production steps to an a certain apparatus (such a condition is hereinafter referred to as “condition that limits use of apparatus”).
- condition that limits use of apparatus the optimum ratio at which each apparatus is used at each production step and for each product type is calculated such that it has an equal load ratio with respect to cumulative processing during an operating period that is the object of a medium-term production plan, thereby reflecting the optimum ratio of use in a short-term production plan.
- a production step under a condition that limits use of apparatus is a bottleneck production step
- no existing method of scheduling has allowed maximization of processing at a bottleneck production step in such a way.

- a tentative target quantity to be processed is set such that a load ratio of each of the group of production steps is leveled between the apparatus or throughout an operating period that is the object of scheduling. This makes it possible to perform processing with the highest efficiency with respect to both of the apparatus and the period under the production plan.
- products are categorized into product types depending on the apparatus used or scheduled to be used at the first production step under the condition limiting use of apparatus, and the tentative target quantity to be processed and/or target quantity to be processed is determined for each of the product types.
- a tentative target quantity to be processed is set for each product type on both of an assumption that only one product type flows through the production step and an assumption that a mixture of product types flows through the production step, and a target quantity to be processed for each product type is determined such that the ratio of the target quantity to be processed of each product type is equal to the ratio of the quantity of work in process that can be actually processed for the product type, such that the sum of the target quantities to be processed of the product types is at a maximum value that is equal to or smaller than the sum of the tentative target quantities to be processed, and such that the target quantity to be processed of each product type is at a maximum value that is equal to or smaller than the tentative target quantity to be processed of the product type.
- each product type in a quantity corresponding to a tentative target quantity to be processed of the product type at the production step minus the quantity of work in process for the product type at the production step is fed with priority from the production step that precedes the production step for which the tentative target quantity to be processed for the product type has been determined, which makes it possible to maximize the processing at the bottleneck production step.
- a tentative target quantity to be processed of a product type introduced on a batch basis or discrete basis is made equal to the quantity of products that form one batch of the product type; a tentative target quantity to be processed of another product type is set at a tentative target quantity to be processed for each product type on an assumption that only one product type flows through the production step; a tentative target quantity to be processed is set based on the quantity of products to form a batch for at least one of the product types; a tentative target quantity to be processed for each product type is set for the other product types on an assumption that only one product type flows through the production step; and a tentative target total quantity to be processed that is the sum of the product types processed at the production step is set such that load ratios of apparatus that are shared at the production step or between production steps including that production step are leveled between the apparatus and throughout an operating period that is the object of scheduling.
